Are computer chips made out of sand?
The small integrated circuits are usually built out of semiconducting materials such as quartz. Computer chips are made of sand, but not just any kind of sand. Scientifically speaking, the term "sand" is an expression of a certain grain size — 0.063 to 2 mm, to be precise. Computer chips are made of silicon, which
